IMPROVEMENT IN LOOMS.

The Schedule referred to in these Letters Patent making part of the same.v

To all whom .tt may concern.:

-. Beitkuown thatI, JOHN JACO HERBERT, of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Looms; and I do hereby declare the following to be a full, clear, and exact description thereof, which Will enable others skilled in the `art to which it appertains to make and use my improvemeut, referencefibeing had to the accompanying drawing which form a part of this specification, and in which- Fgure l is a perspective view ofthe frame-work of my improved loom, showing the driving-gear, the mechanism which actuates the lathe, the improved take-up, and the registering apparatus.

Figure 2 is a sectional view of the cloth-beam, pressing-roller, and sand-paper roller, with the stuft passing over them.

Figure 3 is. a perspective view of the mechanism which actuates the heddles, the cams and levers for driving the shuttles, the spoolin g apparatus, and warpbeam.

'lhe same parts are denoted by the same letters in all the 'figures A is the driving-gear, to which motion-is imparted in any suitable manner, and by which the pinion B, wheel C, shafts D E, and cams F F are revolved.

Tl|ecrank-wl1eel G- on the shaft D is constructed with a s1ot,in which the pit-man H is adjustable by means of a set-screw.

To the pit-man Vis pivoted the vibrating arm I, connected, by the adjustable link K, to the vibrating arm L, to which is-pivote'd the pawl M, which Atakes into the ratchet-wheel N, as does also the pawl 0, pivoted to the frame-work of the loom.

The pinion P ou the shaft of ratchet-wheel N meshes into wheel Q, on whose shaft R are mounted the sandpaper roller S and the wheel T meshing into wheel U. The latter meshes into'wheel V, on whose shaft W is loosely mounted the cloth-beam Y is a roller to press the stui against roller S as it passes to the beam X. v v

rPhe heamX-is provided with .ings a a, in each of which works an adjusting-screw, b,.regulating the teusiou of the spling c, by which theclamp l is pressed against the sliaft-W. The beam X is Vthus clamped to the shaft W so as to revolve with it, while, at the same time, it is free to slip around the shaft whenever its rotation is resistedfby a force greater "than that of the springs c c.

The speed of the take-up may be varied by adjusting the pitman Il andlinhKas the arm L is vibrated.

, By the revolution of the crank-wheel G the pawl INI rotates ratchet-wheel N, which is prevented from slipping back by pawl O. The revolution of the drivinggear thus imparts an intermittent motion to the take- On the shaft E are mounted the cams A A', B' B', and G C', which actuate the, treadles D' D', E E', and F' F. v

',llhe treadles F' E are connected, by Wires, t the heddle-levers G' G G' G', and the treadles -E E' are similarly connected to the heddle-leveis H' H' H H'.

The lower heddle-levers H H' H 'H' are connected, by wires, to the upper- 'heddle-levers I' I K K', from the otherends of which heddles 1 and 2 are suspended by wires, while the lower heddle-levers G G G' G are similarly connected to the upper heddle-levcrs L L M M', from which are suspended heddles 3 and 4.

Heddles land 3 are connected on both sides by cords, whichv pass under pulleys VN N', and' heddles 2 and 4 are similarly connected by cords, which pass under pulleys O' O. These pulleys are connected to coiled springs, which are fastened to the floor or lower frame of the loom.

The rotation of shaft E depresses the treadles by means ofthe cams. When one pair of treadles is de- V pressed the lower heddle-levers to which that pair is attached are also depressed, actuating the vupper heddie-levers attached to them, and thereby raising one pair of heddles. L

The elevation of'one pair of `heddles depresses the other pair .by means of the cords which pass under the pulleys, and the depression of this latterpairractuates the upper heddle-levers, from which theyI are suspended, and thereby elevates the corresponding lower heddle-levers and the treadles attached thereto. The tension of the springs assists the movement of the heddles.

What I claim as my invcntion,and desire to secure by Letters Patent, is-l 1. The cloth-beam, mounted on arotating shaft, and held thereto by theadjustable spring-clamps, substantially as described.

2. rPhe combination, with aheddle-frame, ot' pivoted levers If K' above the frame, and connected, as de'- scribed, to pivoted arms H' H below the frame, and operated by treadles, all arranged'and operating as set forth.

JOHN JACOB HERBERT.
